Claim Tins invention relates to the manufacture of shoes, and more particularly to the treatment of the marginal portions of shoe uppers in lasted position with pressure and is herein illustrated by reference to operations on the ioreparts of shoes, bu it is to be understood that it is also to operations on other portions.

In the manufacture "no-es of a type in which the marginal portion of the forepart of the upper, located between an insole and an outsole, lies, throughout its width in generally parallel relation to the bottom of the last on which the shoe is made, is sometimes advanta eous, especially if an adhesive is used to secure the upper in lasted relation to insole, to subject the marginal portion or" the upper in lasted position over insole to 1"essure and heat. By this treatment any v Likles the of the upper, espe 'ally over the toe end of the insole, are effectively el ninated and a smooth seat close to the insole is ovided to receive the outsole. If the upper is ured adhesively to the insole, moreover, such treatment is usually further beneficial because the heat accelerates the drying or hardening of adhesives such as are commonly used lasting, thus affording increased insurance that the upper will be securely held in lasted position.

In view of the above other considerations, the present invention provides an improved method includin the application of pressure and the marginal po 'tion of upper over an insole, and novel means for use in the practice of the method. in one aspect, an object of the invention is to insure ag st any possible displacement cr loosen of the in the interval between the layi g of its over the insole and the application of the pressure and heat, and to this end the invention provides for pressing upon the insole, and preferably heating, a portion oi the overlaid margin of the upper located at a distance from the extreme edge of the shoe bottom while the portion 1 rer the edge of the shoe bottom is still held unde the overlaying pressure, and for then relea ng from the overlaying pressure the portion nearer the edge and applyin pressure and heat thereto while the pressure on the portion at a distance from the edge is main By this procedure no opportunity is afford for any displaceme of the upper from its final la ted position the pressure a are applied. In the illustrated applica of t invention to the lasting oi the toe ends or" shoes in bed-lasting machine The invention ration February 1, 1935, Serial No. 4,545

(oi. era-a4 the pressure and heat are applied first to a portion of the upper extending inwardly over the insole beyond the edges of the toe-lasting wipers while the wipers are still over the shoe bottom in holding engagement with the upper, after 5 which the wipers are retracted from over the shoe bottom and the portion uncovered by their retractive movement is subjected to pressure and heat. The novel means herein disclosed for thus treating the upper comprises a heated plate 1 formed to engage the upper inwardly of the edges of the wipers and thus to apply the pressure and heat in that location while also preventing any loosening or displacement of the upper from lasted position when the wipers are thereafter retracted, and another heated plate movable into engagement with the portion of the upper uncovered when the wipers are thus retracted. In the construction shown the lastmentioned plate is flexibly conformable to the 0 contour of the shoe bottom and is pressed upon the shoe bottom through a plurality of springcon'trolled plungers. The two plates, as further herein illustrated, are parts of a pressing device which is mounted for movement into and out of a position opposite the bottom of the shoe, but it is to be understood that in some aspects of the invention the pressing device is not necessarily an attached part of a lasting machine.

Further in accordance with the novel method,

in one of its aspects, heat of a higher degree is applied to the portion of the overlasted margin the pressure, without danger that any portion which might be visible in the finished shoe will be damaged by the heat. To carry out this part of the method, the plate which engages the upper inwardly of the edges of the toe wipers in the novel pressing device herein shown has an e1ectrical heating unit mounted therein, by which also the plate which engages the upper nearor the edge of the shoe bottom is heated but to a lower degree than the other plate by reason of its comparative remoteness from the source of heat and the manner in which it is constructed and mounted. The invention further provides for the application of relatively greater pressure to the inner more wrinkled portion of the mar- This afifords better insurance that the 35 gin of the upper where greater pressure is desirable than nearer the edge of the shoe bottom.

The novel method and novel features of the means herein disclosed for use in the practice of the method will now be more particularly described by reference to the accompanying drawings and pointed out in the claims.

In the drawings,

Fig. 1 is a perspective View of a portion of a bed-lasting machine having upper-pressing means constructed in accordance with the present invention for the practice of the novel method, the parts being shown in the positions which they occupy when the pressing means is first applied to the shoe in engagement with the portion of the upper which extends inwardly beyond the edges of the toe wipers;

Fig. 2 is a vertical section longitudinally of the shoe, showing the pressing device with the parts in the same positions as illustrated in Fig. 1;

Fig. 3 is a vertical section laterally of the shoe showing the lower portion of the pressing device with the parts in the same positions as shown in Figs. 1 and 2; and

Fig. 4 is a section similar to Fig. 3, but showing the parts in the positions which they occupywith the pressing device in engagement also with the portion of the upper uncovered by retractive movement of the toe wipers.

The bed-lasting machine herein shown as having upper-pressing means constructed in accordance with the present invention is one of a wellknown type characteristic features of which, relatingespecially to the means for lasting the toe end of the shoe, are illustrated and described in detail, for example, in United States Letters Patent No. 1,284,870, granted on November 12, 1918 upon an application of Matthias Brock. Only a portion of the machine, therefore, is included in the drawings and only such parts as it is necessary to refer to for an understanding of the invention will be hereinafter mentioned. It is further to be understood that the invention is not limited to machines of the particular type illustrated or to use with such machines.

The shoe and its last are mounted as usual at the heel end on a jack (not shown), and at its forepart the'shoe is supported on a toe rest l0 against downward pressure on its bottom face. The shoe thus supported is operated upon at the toe end by toe-embracing wipers [2 which, in machines of the illustrated type, are moved upwardly by a treadle to wipe the toe end of the upper heightwise of the last to the edge of the shoe bottom and are advanced and closed by a hand lever to wipe the marginal portion of the upper inwardly over the insole, the shoe herein shown being one of a type in which the marginal portion of the upper is thus wiped inwardly over the insole so as to lie throughout its width in substantially parallel relation to the bottom of the last. The machine shown further includes a toe band M (Fig. 1) for embracing and clamping the upper against the last near the edge of the shoe bottom in the manner disclosed in the above-mentioned Letters Patent, although such a toe band may be and often is omitted. For convenience it is not shown in Figs. 2, 3 and 4.

For purposes of the present invention the machine is provided with an upper-pressing device supported as hereinafter described for movement into and out of position over the bottom of the forepart of the shoe and having two upperpressing members or plates l6 and I8 (Figs. 2, 3 and 4). The plate IS in the construction shown is a rigid plate curved similarly to the edge of the portion of the shoe bottom along which the plate extends and so formed as to engage and press upon the insole, as shown in Figs. 2 and 3, that portion of the upper which extends inwardly over the insole beyond the edges of the wipers 52 while the wipers are still over the shoe bottom in holding engagement with the upper. This plate is heated by an electrical heating unit 20 mounted therein, to which an electrical current is conducted through wires in a flexible cable 22 (Fig. 1). The plate i6 is pressed down upon the shoe bottom through a spring 24 by downward movement of a supporting plate 26 between which and the plate IS the spring is mounted. A portion of the plate it extends outwardly beyond its central upper-engaging portion in spaced relation to the shoe bottom, and in openings formed in this outwardly extending portion of the plate are a plurality of spring-controlled plungers 28 arranged in a series along the edge of the shoe bottom. To the lower ends of these plungers is riveted the upper-pressing plate it to which heat is conducted from the heating unit 28 through the plate 66 and the plungers. The plungers 28 have stems 30 of smaller diameter which extend upwardly through holes in the supporting plate 26 and have mounted thereon springs 32 through which downward ressure is transmitted from the plate 28 to the plungers. The lower ends of the plunger 28 are diametrically enlarged for engagement with downwardly facing shoulders 34 on the plate l 6, and the stems 39 at their upper ends a're provided with cotter pins 36 arranged to engage washers 38 on the top of the plate 25. By this means accordingly relative separating movement of the plate 3 and the plate 25 under the influence of the 24 is limited, the parts being initially so positioned that the upper-pressing plate I8 is upraised a substantial distance above the upper-engaging face of the plate l 6, so that the latter may be plied to the upper while the wipers are over the shoe bottom, as illustrated in Figs. 2 and 3. The plate !6 is pressed down upon the margin of the upper through the spring 24 as hereinabove described, and thereafter as the plate 26 is further depressed against the resistance of this spring the several plungers 28 are moved downwardly to apply the pressing plate E3 to a portion of the upper which is exposed by retractive movement of the wipers from over the shoe bottom while the plate 15 is holding the upper securely in lasted position.

The plate I8 consists of a comparatively thin strip of metal curved lengthwise similarly to the edge of the shoe bottom and lying close to the central upper-engaging portion of the plate I 6. The plate 18 is preferably flexible and resilient, so that it conforms itself to the contour of the shoe bottom as it is pressed downwardly by the several plungers 28. It will be understood that at the end of the downward movement of the plate 26 the several springs 32 controlling the plungers 28 are substantially compressed. The plates l6 and I8 thus cooperate to apply pressure and heat substantially throughout the width of that portion of the upper which is lasted inwardly over the insole. In the construction herein shown these plates are arranged to act not only upon the margin of the toe portion of the upper lasted inwardly by the wipers 2, but also upon a portion of the upper extending substantially as far rearwardly as the ball line of the shoe. The forepart of the upper at the rear of the toe portion may have been already lasted before the shoe is presented to the bed-lasting machine, or may be lasted by hand while the shoe is in this machine preparatory to the use of the pressing device on the upper. While it will be evident that the steps performed at the rear of the toe portion are not precisely thesame as at the toe portion, because the upper beyond the ends of the toe wipers is not held under overlaying pressure when the plate i5 is applied thereto, nevertheless the heated plates l6 and I8 act in other respects with substantially the same beneficial effects at the rear of the toe as at the toe portion, especially if the forepart at the rear of the toe is lasted with adhesive.

The plate !8 is heated to a lower degree than the plate it, partly because it is comparatively remote from the heating unit 29 and partly because the plungers 28, through which the heat is conducted, are spaced apart and are mounted somewhat loosely in the holes in the plate IS. The comparatively thin plate [8, moreover, tends to dissipate the heat more rapidly than the plate is. It is accordingly practicable to apply to the upper through the plate lfiheat of a considerably higher degree than could safely be applied at or near the edge of the shoe bottom because of danger of damaging a portion of the upper which might be visible in the finished shoe; and this is desirable as aifording better insurance that the inner portion of the overlasted margin of the upper, where wrinkles due to the gathering of the margin around the toe are most prominent, will be effectively smoothed by the shrinking action of the heat. Provision is further afforded for the application of greater pressure to the inner more wrinkled portion of the margin of the upper than to the portion near the edge of the insole where excessive pressure might have the undesirable effect of squeezing or spreading the upper in an outward direction. For this purpose the spring 24 through which the inner plate i6 is pressed down on the shoe bottom is considerably stronger and is subjected to greater compression by the plate 26 than each of the springs 32 acting respectively on diiferent portions of the flexible plate IS.

The plate 25 in its downward and upwardmovements relatively to the plate i5 is further guided by pins 58 and 42 which extend upwardly from the plate it into tubular projections 44 and 45 on the lower side of the plate 26. The plate 26 and other portions of the upper-pressing device are supported on one end of an arm or carrier 48 which is slidingly movable lengthwise in a holder 59 supported on a vertical rod 52. The arm 48 has a ball-shaped forward end 54 which lies in a concave seat formed in. the upper face of the plate 28, as shown in Fig. 2, and secured to this plate is a bracket 56 which extends over the top of the ball-shaped end 54 to support the pressing device on the arm 58. It will be evident that this construction permits the pressing device to be turned horizontally about the ball-shaped end 5% to assist in positioning the device in proper relation to the shoe bottom and also permits universal tipping movements of the device so that the plate is may adjust itself to the bottom of the shoe. Projecting from the plate 25 is a handle 58 to assist the operator in properly positioning the device, and secured to the arm 48 is a curved arm til which underlies the handle 58 and assists in preventing excessive tipping movements of the pressing device when the latter is in its idle position. The holder 58 and the rod 52 are of substantially the same construction and are operated in the same way as means provided heretofore in machines of the illustrated type for supporting a holddown member and for pressing the member down upon the shoe bottom, as disclosed in Letters Patent No. 1,120,822, granted on December 15, 1914 upon an application of E. L. Keyes. As more fully illustrated and described therein, the holder 58 is mounted to turn about the rod 52, and the rod is moved downwardly by means of a treadle connected thereto and is locked in its depressed position. Accordingly, in the construction herein shown, the provision for turning movement of the holder 55 about the rod 52 permits the operator to swing the upper-pressing device from an initial idle position at the rear of the machine to a position over the bottom of the forepart of the shoe, after which, by use of the treadle, the operator moves the rod 52 and the holder 58 downwardly to apply the plate l5 first to the shoe and thereafter to apply the plate l8'to the shoe in the manner hereinbefore described. Further to assist in positioning the pressing device in proper relation to the shoe before it is applied to the shoe the construction shown includes a lever 52 which is pivotally mounted on that portion of the arm 48 which is slidingly movable in the holder 58, the lever having a pin-and-slot connection at 64 with the holder 58. By use of this lever the operator may slide the arm 48 forwardly or rearwardly in the holder 58 as desired.

The steps-leading up to the use of the upperpressing device on the shoe will vary in accordance with the preferences of different manufacturers. Commonly, however, in lasting toes with an adhesive the several layers of upper materials,

including the lining and the toe box, are first wiped upwardly around the toe end of the last by the wipers l2 and the marginal portions of the several layers are then wiped preliminarily inward over the insole by the wipers. Thereafter the wipers are retracted from over the shoe bottom and by use of a hand knife the operator trims the margin of all the layers except the outer layer approximately as far back as the edge of the insole. He then applies a suitable adhesive to the margin of the outer layer or to both, and wipes the upper materials again upwardly and wipes the margin of the outer layer inwardly over the insole into position to be secured by the adhesive. If the forepart of the shoe rearwardly of the toe portion has not ready been lasted before the shoe comes to the machine, the operator will perform the lasting operation in that location by hand before or after lasting the toe portion, preferably using adhesive to secure the upper to the insole. While the toe wipers are still over the shoe bottom in holding engagement with the upper over an area extending a substantial distance inwardly from the edge of the shoe bottom, the operator swings the upper-pressing device into position over the bottom of the forepart of the shoe, adjusts it in proper relation to the shoe, and lowers it by the treadle connected to the rod 52 for that purpose to bring the inner heated pressing plate it into engagement with a portion of the overlasted margin of the upper which extends inwardly beyond the edges of the wipers, as illustrated in Figs. 1, 2 and 3. Thereafter, while the plate It is in pressing and holding engagement with the margin of the or to the insole,

upper, the operator retracts the wipers l2 from over the shoe bottom and by further depression of the treadle forces the plate 26 downwardly against the resistance of the spring 24 to apply the outer flexible pressing plate l8 to the portion of the upper uncovered by the retractive movement of the Wipers. The downward movement of the plate 25 is continued until the several springs 32 are substantially compressed in order to apply sufficient pressure to the plate l8. It will be evident that through the comparatively heavy spring 24 the plate 56, which acts on the more wrinkled inner portion of the gathered margin around the tee, is forced against the upper with greater pressure than is applied through the springs 32 to the plate it, a relatively higher degree of heat also being applied to the upper by the plate 56 as hereinbefore explained. The pressing plates it and i 8 are maintained in pressing engagement with the upper as long as desired, after which the pressing device is withdrawn from the shoe and returned to its idle position. The plates may, for example, be left in contact with the shoe while the operator lasts the heel end of the shoe in the customary manner, if the heel end has not already been lasted.
